Hello Ava and Aubrey,

This is Lt. Paul Barbour from Edmond P.D. I work the night shift and patrol neighborhoods and look for criminal activity. We do this so people can sleep and [sic] night and not worry about their safety.

I was driving through your neighborhood and everything looked good! I wanted to drop you a note to let you know all is well!
